2.2 One-Way Functions: Definitions
In this section, we present several definitions of one-way functions. The first version, hereafter referred to
as strong one-way function ... one-way function), is the most convenient one. We also present weak
one-way functions which may be easier to find and yet can be used to construct strong one way functios,
and non-unifo...

respectively. Then prove that the functions f and g ◦ f are one-one but g is not one-one.
Solution: By definiton, it is clear that f is indeed one-one and g is not one-one. But
g ◦f(x) = g(f (x)) = g(2x) ... one-to-one then the function g ◦ f is also one-to-one.
3. If f and g are onto then the function g ◦ f is also onto.
Proof. First note that g ◦f : A−→C and both (h ◦g) ◦f, h ◦...
